Workout Trends — Fad or Here to Stay?

Going through the same workout routine can be boring, which is why new products and methods keep people motivated to get fit. However, with so many options, it's hard to anticipate which technique or method will stick around and influence gym workouts nationwide. Now's your chance to vote on the workout equipment you think is a fad versus the ones that you are convinced are here to stay.

I've tried a few of them (TRX was the hardest!), and I think a few of them are here to stay depending on how much results they can actually produce. I just tried Krav Maga, this self-defense fitness class that mixes in street fighting techniques with cardio, and wrote a feature about it. Maybe a fad? Check it out and see if it's a class that would interest you: http://www.greatist.com/fitness/krav-maga/
